To all whom it may concern:

Be it known that L-CHARLES MoCoY, a citizen of the United States,residing at Wmnipeg, in the Province of Manitoba, D0

minion of Canada, have invented a new and useful Cooler forRefrigerators, of which ing in contact therewith will be cooled and mylmproved refrigerator with the doors of.

forcibly hurled therefrom to thereby create a forced draft of cooled airwithin the refrigerator.

A further object is to provide an improved form of rotatable tankadapted to contain a freezing mixture therein whereby the said mixturewill be agitated to lower the tem perature thereof. 7 I.

With the foregoing and other Ob ects-m view which will appear as thedescription preceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes inthe preciseembodimentof the invention herein disclosed, can be made within thescope of what-is claimed, without departing from the spirit of theinvention.

In the drawings accompanying this specification and forming a partthereof, the preferable form of my invention is illustrated, in whichFigure 1 isa front view in elevation of the cooling compartment open todisclose thecooling means disposed therein. Fig; 2 is a plan view of thetank. Fig. 3 is a fragmentary vertical cross sectional view taken throuh the center of the said tank.

tratedin Fi l of the drawings in an open position. T 'e' improvedcooling apparatus herein described is illustrated in the ice compartment2 but it is to be understood that it may be applied with equal facilityto refrigerators, ice boxes, or cold storage rooms, etc, taking theplace of the ice which is ordinarily disposed therein.

The cooler into which the freezing mixture and ice is placed comprisesthe central portion 4 communicating with which and extending therefromare the four wings 5. Each of the said wings is provided with a hingedlymounted lid or cover 6 with a: suitable latch 7 secured thereto wherebythe cover may be held in a closed position. The cooler which is in theform of a tank or receptacle is provided with the circular flue 8extending centrally .therethrough and through which flue extends thevertical shaft 9 which is adapted to, support the said cooler orreceptacle in a rotatable manner.

the central portion of the cooler is considerably larger than the shaft9 so as to provide an air circulating conduit through the centralportion of the cooler whereby an .increased radiating surface will beprovided in the cooler receptacle.

The shaft 9 is disposed within suitable bearings 10 secured to the upperand lower walls of the compartment 2 and rigidly secured to the shaft 9adjacent the lower extremity thereof is a belt wheel 11 around whichpasses the drivlng belt 12, the latter passing over the pulley of amotor 13, whereby the said shaft 9 may be mechanically operated. Rigidlysecured to the upper and lower ends of thecooling receptacle 4: are thecross members 14 which are adapted to en gage the shaft 9 and to holdthe said cooler receptacle rigidly thereto whereby the same will berotated by the rotating of the shaft. The motor 13 which represents asource of power is adapted to drive the cooler by gearing or a frictionbelt 12 which actuates the shaft 9 to thereby rotate the cooler, itbeing pointed out that the belt is illustrated as a driving mechanism asbeing .silent in operation and practically noiseless. By rotating thesaid cooling receptacle, the wings 5 thereof willcome' forcibly against.the surrounding air and will thereb cool the same and create a forceddraft w ich will circulate throughout the various portions of therefrigerator to effectual 1y cool the same. The air will also circulatethrough the centre-'1 lllu flue 8 and will be cooled through the saidpassage, it being noted that the air will be cooled and at the same timewill remain in a dry and sanitary conditioninasmuch as it does not comedirectly into contact with the ice and freezing mixture which isdisposed within the cooling receptacle 5.

The top cover 1s provided with lids 6 communicating with the variouswings of the cooler and through which the ice and freezing mixture is tobe introduced. The mixture -which is introduced within the saidreceptacle or compartment of the cooler is adapted to absorb the heatfrom the walls of the cooler and from the surrounding air. with theresult thata considerable lowering of temperature will be obtained andthat by a rotatlng of the said cooler, the. various ingredients willmore readily pass into solu- =-tion to thereby absorb the heat asdescribed.

'From the foregoing it will be apparent that the rotating of the coolerperforms the functions and produces the eflect of increased radiation bybringing the air forci- -'bly into contact with the side walls of thecooler and to create a forced draft throughout the various parts of therefrigerator and also tends to agltate material disposed within thecooler, to aid the same in passing into solution, and to further bringthe various materials into more intimate contact' to thereby eflect alowering of temperature. By extending the four wings 5 radially from thecentral portion 4, it allows the various ingredients disposed therein tobe thrown forcibly against the outer extremities of the said wings' andto thereby produce the greatest cooling effect at these points, andwhich points are also the ones which being the farthest from the centerof the rotating cooler, contact with a relatively greater amountof airthan the portions more centrally disposed.

From the foregoing itv will be apparent that refrigeration may beobtained with or 'witliout the use of ice and that furthermore when usedin connection with ice, the most eflicient and economical refrigerationwill be obtained, it being' pointed out that when it is desired toconsiderably lower the temperatureat any time, the motor may be startedand the same rotating the cooler will agitate the various ingredientsdisposed within the said cooler to immediately reduce the temperature,as described.

Mention is also made of the fact that the cooler may be used to coolrooms, public buildings, etc.

Havin thus fully described the invention what Iaaim to benew andoriginal with me is:

1. In an'apparatus of the class described,

the combination of a refrigerant receptacle with outstanding wingscommunicating therewith, a central flue extending longitudinally throughthe said receptacle and providing an air passage therethrough, a

ed to rotatably support the said receptacle, means for rotating the saidreceptacle to bring the wings thereof forcibly in contact with thesurrounding air to create a positive draft and to cool'the' same.

2. A refrigerant receptacle including a main compartment with a'centralflue extendin there through and ositi'oned substantia ly vertical, aplurahty of radially extending wings communicatmg with said maincompartment and with't'he longitudinal axes thereof substantiallyparallel to the longitudinal axis of the said flue, and

means extending through said flue for the supporting of said receptacle.

3. In an apparatus of the class described, a main compartment providedwith a central flue extending therethrough, a shaft extending throughsaid flue, and means engaging the said shaft and the said compartment'for securing the said compartment thereto,

radially extending wings; communicating with the main compartment andwith their longitudinal axes substantially parallel to extending throughsaidflue, means for holding said shaft in a verticalposition, meansengaging said receptacle and said shaft for support-ing the receptacleout of contact with adjacent objects and to permit the circulation ofair through the said flue, the adjacent surfaces of the walls of theradial wings forming reentrant angles, the said walls acting to cool theair in contact therewith and to set up a circulation of air downwardlypast the said walls and up through the central flue.

In testimony that I claim the foregoing as my own, I have hereto aflixedmy signature in the presence of two witnesses.
